From: Houston, TX
P0191 Fuel Rail Pressure Sensor Performance
P0251 CP3 Pump Regulator Control
P2769 Transmission TCC Control Circuit Low

You can get a list of DTCs on this site link:

Seems the other two are assoicated with rail pressure sensor and/or cp3 regulator. I would check the rail pressure sensor connections first and go from there.
